Answer:
2. <em>A reference of type A can be treated as a reference of type B</em> - False
Base class or its objects are not related to their derived class (or its objects).
Explanation:
class A {
int a;
public A() {
a = 7;
}
}
class B extends A {
int b;
public B() {
b = 8;
}
}
///////////////////////////////////////////////////////////////////////////////////////////////////////
1. <em>After the constructor for class B executes, the variable a will have the value 7 </em>- True.
When an object of a derived class is declared, the constructor of base class is called before the constructor of derived class (is called).
3. <em>Both variables a and b are instance variables </em>- True.
Classes can have instance, or member, variables and methods.
4.<em> After the constructor for class B executes, the variable b will have the value 8</em> - True.
When object of class B is declared, its constructor was called, which initialized variable b to 8.

Answer:
Aye dog I don't know nothing about code, yes its true, but I hope that you get an answer for you!

Answer:
- Operating System.
- Laptop.
- Convertible computer.
- Peripheral.
- Desktop Computer.
Explanation:
Operating system is a software that manages the hardware and the software in the system and provides the interface between machine and the user.
Laptops are the portable computing devices which you can carry with you.
Convertible computer have a keyboard that is detachable and can be converted into a tablet.
Peripherals are devices which we can attach to the computer.
Desktop computer is a computing device that not portable at all.
Answer:
//class Name
class Name {
// attributes gave you 3
String first_name;
String last_name;
int length = 0;
//constructor with 2 parameters
Name(String first_name, String last_name){
}
//methods
public String find_printed_name(){
return first_name + " " + last_name;
}
public void find_sortable_name(){
return last_name + ", " first_name.charAt(0);
}
public static void main(String[] args){
// instantiate the class
Name test_name = new Name("David", "Joyner");
System.out.println(test_name.first_name);
System.out.println(test_name.last_name);
System.out.println(test_name.find_printed_name());
System.out.println(test_name.find_sortable_name());
}
Explanation:
You didn't specify a language so I did it in Java.
You should know how to declare methods in Python.
